Sorry about your camera.
Unless you're really burning for something new, which it sounds like you're not: you should just get another d90 used, like on craigslist: $350-$500.
D90 is a sweet camera and you know how its supposed to work so put it through its paces before you buy. D7000 is definately an upgrade but its also heavier and less comfortable for my hands. For me its not $500 better than a d90.
